Mc Cable Cable connectors reach boxes or plates for a safe and indicator connection. MC cables really need a high -quality conductor because they constantly need to support the grounding path and are often used in difficult conditions. In this guide, we discuss standard MC cable connectors to help you take the best option for your electric app.
Types of MC cable connectors and their use cases
1. Set-SCREW connectors
MechanismUse one or more screws to install them on the MC cable shield.
material: Zinc, steel, or metal casting.
The scope of the cable size: 3/8 “to 2” trade sizes.
Using the caseCommercial and residential facilities for general purposes.
Performing exampleConnecting Cable 12/2 MC to an intersection box in the lighting system in the retail store.
2. pressure connectors
MechanismUse tightening pressure nuts to secure the conductor to the MC shield.
material: Zinc or steel.
The scope of the cable size: 1/2 “to 2”.
Using the case: The areas where the vibration is present or need to seal a more strict.
Performing example: It is used in manufacturing facilities where the vibrations of the equipment can reduce the specified screws.
3. Snap-in connectors
MechanismTooless stabilization with the spring tension segment settles in place.
material: Zinc or compound metal.
The scope of the cable sizeUsually 3/8 “and 1/2”.
Using the caseFast installations in pre -pregnancy pre -pregnancy panels and boxes.
Performing example: It is used in large residential complexes, where electricity needs to complete the additions quickly across many units.
4. The right corner connectors (90 degrees)
MechanismAvailable in the Set-SCREW collection, pressure or amazing patterns, but with an angle of 90 degrees.
material: Zinc or steel.
The scope of the cable size: 3/8 “to 2”.
Using the case: Stabilizing the narrow space as the straight connectors are not suitable.
Performing exampleMc cable guidance in the roof tributaries or behind the devices.
5. Duplex (double) connectors
MechanismUnderstand two MC cables through one installation.
material: Zinc dies casting or steel.
The scope of the cable sizeUsually for 3/8 cables “or 1/2”.
Using the case: When two circles need to enter the square by the lying of the defeated.
Performing exampleDouble lighting circuits that enter the switch box in a commercial space.
6. isolated throat connectors
MechanismThis can be any style (Set-SCREW, pressure, etc.) with a soft plastic insert to protect the conductors.
material: Zinc or steel with heat throat.
The scope of the cable size: 3/8 “to 2”.
Using the caseWhere the conductor should be protected from sharp metal edges.
Performing exampleData centers or office space with low -voltage wires.
7. Armored ground bushings
MechanismAdditional connectors to provide grounding continuity with bonding screws.
materialAluminum or galvanized steel.
The scope of the cable size: To use with MC cables up to 4/0.
Using the case: MC Cables without an integrated floor where a separate bonding is required.
Performing example: It is commonly installed in hospitals and laboratories to comply with NEC 250.118 and 517.13, which require continuous grounding paths for patient care areas.
8. MC Liquidtight connectors
Mechanism: Compressed pressure or gland connectors with fillings and episodes O.
materialNicker, zinc or stainless steel.
The scope of the cable size: 1/2 “to 2”.
Using the case: Moist or external environments to prevent moisture from entering.
Performing exampleHVAC units on the surface or external lighting connections.
9.
MechanismSimilar to the pressure with the PVC jacket to resist corrosion.
materialSteel or zinc with PVC coating.
The scope of the cable size: 1/2 “to 2”.
Using the case: Harsh or erosion environments such as naval infantry.
Performing exampleMc finishing a cable in the wastewater treatment facility.
10. EMT/MC collection connectors
Mechanism: The dual function conductor that suits both MC and EMT cable.
material: Zinc or steel.
The scope of the cable size: 1/2 “to 1-1/4”.
Using the caseHybrid installation operations using both EMT and MC.
Performing exampleIndustrial settings with EMT in exposed strides and MC cable in the walls.
11. MC-PCS cable connectors
MechanismDesigned to accommodate both the power control and low voltage control wires in the MC-PCS cable.
material: Zinc or steel alloy with a soft or huge throat.
The scope of the cable size: 3/8 “to 1/2”.
Using the caseLED lighting systems and control with ancient circles 0-10 volts.
Performing exampleLighting elements in commercial buildings using SMART or controlled SMAR lamps.
Choose the appropriate size for MC cable connectors
Check out OD (outer diameter) MC cable (outer diameter)– Usually listed in the specifications paper.
Consent it with the scope of the size of the conductor– The associations are classified with a set of diameters that you absorb.
Below is the rough guide to change the size of the MC cable conductor:
How to choose MC cable connector
Check the size of the cable
match OD D (OD) From your MC cable to the scattered conductor range (for example, 3/8 “, 1/2”, etc.).
For example, the 12/2 MC cable has an OD with about 0.45 inches, which is ideal for MC 1/2 connector.
Determine the type of cable and special requirements
Is it Standard MCand MC-PCSand MC-HLOr another variable? Choose a specially designed conductor for this type:
MC-PCS It requires smooth tap connectors to separate the sign/energy
MC-HL It needs an explosion resistance, and dangerous equipment.
HCF MC Batins may require interrelationship.
If this is just regular MC Cable, You can choose from a wide range of available conductors discussed in this post.
Mosul match with the environment
Use Liquid tight or PVC The conductors are in the environments exposed to moisture or spraying salt or chemicals – such as roofs of coastal buildings.
Calculate guidance and space restrictions
Use 90 ° right angle connectors When directing cables around the corners, behind the equipment, or in low ceilings.
Choose your contact method
Decide between Set-SCREW (Fast, standard), pressure (Safety), or Snap-in (Less tools, fast installation).
Check the compatibility with Mosul materials
Make sure to classify Mosul copperand AluminumOr both of themEspecially if the cable is using aluminum connectors.
Select the right conductor depending on the application
Use Zinc or He dies For general use, Stainless steel To resist corrosion, and Copper or Antibiotic alloys Where the MC-HL cable will be used.
Ensure NEC and UL compliance
Check the conductor The menu on MC Cable It meets with the ability to apply Nec requirements (For example, NEC Article 330, NEC 501.10 for MC-HL).
Protection of Mosul insulation when needed
Nassau National Cable provides a wide catalog of MC cables, including standard Aluminum MCand Copper mcand HCF MCAnd MC-HL Residential, commercial and industrial use options. You can also find the right Conductors For each type of MC cable in our store.
